Since the limit of the sequence is 0, we can say that the sequence is bounded between 0 and some positive number (since all terms in the sequence are positive). Therefore, the answer is (A) bounded.
To determine whether the sequence is increasing, decreasing, or not monotonic, we need to look at how the terms in the sequence change as n increases.
We can rewrite the sequence as:
an = 1/(5n + 4)
As n increases, the denominator 5n + 4 also increases, which means that the fraction 1/(5n + 4) decreases. Therefore, the terms in the sequence decrease as n increases.
So the answer is (B) decreasing.
To determine whether the sequence is bounded, we need to consider the limit of the sequence as n approaches infinity.
lim (n→∞) an = lim (n→∞) 1/(5n + 4) = 0

The matrix of the linear transformation t : R4 → R3 defined by t(x1, x2, x3, x4) = (2x1 3x2 x4, 5x1 9x3 − x4, 4x1 2x2 − x3 7x4) is:
| 2 0 0 0 |
| 0 0 5 -1 |
| 4 8 -2 7 |
To determine the matrix of the linear transformation t : R4 → R3, we need to find the image of the standard basis vectors under the transformation t. The standard basis vectors of R4 are e1 = (1, 0, 0, 0), e2 = (0, 1, 0, 0), e3 = (0, 0, 1, 0), and e4 = (0, 0, 0, 1).
Applying the transformation t to each of these vectors, we get:
t(e1) = (2, 0, 4)
t(e2) = (0, 0, 8)
t(e3) = (0, 5, -2)
t(e4) = (0, -1, 7)
Thus, the matrix of the linear transformation t with respect to the standard bases of R4 and R3 is:
| 2 0 0 0 |
| 0 0 5 -1 |
| 4 8 -2 7 |
Each column of this matrix represents the image of the corresponding basis vector of R4, expressed as a linear combination of the basis vectors of R3.
Note that the matrix has 3 rows and 4 columns, reflecting the fact that the transformation maps R4 to R3.
The first column represents the image of the first basis vector e1, which is (2, 0, 4) in R3.
Similarly, the second, third, and fourth columns represent the images of the basis vectors e2, e3, and e4, respectively.
Therefore, the matrix of the linear transformation t : R4 → R3 defined by t(x1, x2, x3, x4) = (2x1 3x2 x4, 5x1 9x3 − x4, 4x1 2x2 − x3 7x4) is:

find the area under the standard normal curve between z=−1.15z=−1.15 and z=2.84z=2.84. round your answer to four decimal places, if necessary
The area under the standard normal curve between z = -1.15 and z = 2.84 is 0.8726.
How to find the area under the standard normal curve?To find the area under the standard normal curve between z = -1.15 and z = 2.84, we need to use a standard normal distribution table or a calculator.
Alternatively, we can use a software program such as R or Python to find the area.
Using a standard normal distribution table, we can find the areas to the left of z = -1.15 and z = 2.84, and then subtract the smaller area from the larger area to find the area between the two z-values.
From the table, we find:
The area to the left of z = -1.15 is 0.1251
The area to the left of z = 2.84 is 0.9977
Therefore, the area between z = -1.15 and z = 2.84 is:
0.9977 - 0.1251 = 0.8726
Rounding this to four decimal places, we get the final answer of 0.8726. Therefore, the area under the standard normal curve between z = -1.15 and z = 2.84 is 0.8726.

how many strings of length four can be formed using the letters abcde if repetitions are not allowed?
There are 120 strings of length four that can be formed using the letters abcde if repetitions are not allowed.
Since repetition is not allowed, we can use the counting principle to determine how many chains of four can be formed from the letters abcde.
The primary position has five choices (a, b, c, d, or e). For the second position, he has 4 choices (because he cannot use the letter he chose for the first position).
The third position has three choices and the fourth position has two choices.
Utilizing the increase guideline, able to multiply the number of choices for each position to urge the overall number of conceivable strings.
5x4x3x2 = 120

determine whether the integral is convergent or divergent. 3 30 x2 − 7x 10 dx 0
To determine if the integral is convergent or divergent, we need to evaluate the given integral. Integers are a type of number in mathematics that include both positive and negative whole numbers, as well as zero.
Here's the integral you provided:
∫(from 0 to 3) [(30x^2 - 7x)/10] dx
First, let's simplify the integer and by dividing each term by 10:
∫(from 0 to 3) [3x^2 - (7/10)x] dx
Now, we need to find the antiderivative of the simplified integrand:
Antiderivative of 3x^2 is x^3, and the antiderivative of (7/10)x is (7/20)x^2.
So, the antiderivative of the integrand is:
x^3 - (7/20)x^2
Next, we'll evaluate the antiderivative at the limits of integration (0 and 3):
(x^3 - (7/20)x^2) | (from 0 to 3)
= (3^3 - (7/20)(3^2)) - (0^3 - (7/20)(0^2))
= (27 - (7/20)(9)) - (0 - 0)
= 27 - (63/20)

If the product of two integers is 27 x 38 × 52 × 711 and their greatest common divisor is 23 x 34 x 5, what is their least common multiple?
The least common multiple of the given two integers is 24804834 if the product of two integers is 27 x 38 × 52 × 711 and their greatest common divisor is 23 x 34 x 5.
We can use the formula
LCM(a, b) = (a * b) / GCD(a, b)
where LCM(a, b) is the least common multiple of a and b, and GCD(a, b) is their greatest common divisor.
We are given that the product of the two integers is
27 x 38 x 52 x 711
We can factor this into its prime factors
27 x 38 x 52 x 711 = 3^3 x 2 x 19 x 2^2 x 13 x 3 x 59 x 79
The greatest common divisor of the two integers is
23 x 34 x 5 = 2^2 x 5 x 23 x 17
We can now use the formula to find the least common multiple
LCM = (27 x 38 x 52 x 711) / (23 x 34 x 5)
LCM = (3^3 x 2 x 19 x 2^2 x 13 x 3 x 59 x 79) / (2^2 x 5 x 23 x 17)
Simplifying, we can cancel out the common factors of 2, 5, 23, and 3
LCM = 3^2 x 2 x 19 x 13 x 59 x 79 x 17
LCM = 24804834
Therefore, the least common multiple of the two integers is 24804834.

Calculate the cost if Thato uses 35 kl of water charge 2.4.2. Calculate the new fixed charge if it is increased by 15%
Answer:
The cost for Thato's usage of 35 kl of water is R702.48.
Step-by-step explanation:
Since Thato used 35 kl of water, she falls into the third category where the rate is R16.20 per kl. We can calculate the cost as follows:
Cost = Fixed charge + (Rate per kl × Usage) + Infrastructure fee
The fixed charge is free for infrastructure, so we don't need to include it in this calculation.
Cost = (Rate per kl × Usage) + Infrastructure fee
= (R16.20 × 35) + R7.15
= R567.00 + R7.15
= R574.15
We also need to add 15% VAT to the cost:
Total cost = Cost × (1 + VAT)
= R574.15 × 1.15
= R702.48
Therefore, the cost for Thato's usage of 35 kl of water is R702.48.
2.4.2. Answer: The new fixed charge would be R92.81.
Explanation:
If the fixed charge is increased by 15%, the new fixed charge would be:
New fixed charge = Old fixed charge + (15% of old fixed charge)
= R80.70 + (0.15 × R80.70)
= R80.70 + R12.11
= R92.81
Therefore, the new fixed charge would be R92.81.

Let A and P be square matrices,
D. det(PAP-1) = [(det P) (det A) (det P-1)]-1.
To show that det(PAP-1) = det A,
we can use the property of determinants that states det(AB) = det(A)det(B) for any matrices A and B.
We can rewrite PAP-1 as (P-1)-1APP-1, and then use the property of determinants to get:
det(PAP-1) = det((P-1)-1APP-1)
det(PAP-1) = det(P-1)-1det(A)det(P-1)
Since P is invertible, det(P) ≠ 0 and we can multiply both sides of this equation by det(P) to get:
det(P)det(PAP-1) = det(A)det(P-1)det(P)
Using the property of determinants again, we can simplify this equation to:
det(PAP-1) = det(A)det(P-1)
Finally, we can substitute det(P-1) = 1/det(P) into this equation to get:
det(PAP-1) = det(A)(1/det(P))

The confidence interval of 99% for μ₂ - μ₁ for the given mean and standard deviation is equal to (23.7377, 49.7713).
Confidence interval = 99%
Confidence interval for μ₂ - μ₁, we need to follow these steps,
Calculate the sample mean difference and the standard error of the mean difference.
Sample mean difference
= ¯x₂ - ¯x₁
= 162.75 - 126
= 36.75
Standard error of the mean difference
= √[(s₁^2/n₁) + (s₂^2/n₂)]

By using linear approximation formula the estimation g(1.99) and g(2.01) of g(2) - 5 and g'(x) = Vx^2 + 5 are 4.91 and 5.09, respectively.
We can use the linear approximation formula, which is:
L(x) = f(a) + f'(a)(x-a)
Where L(x) is the linear approximation of f(x) at a,
f(a) is the value of f(x) at a, f'(a) is the derivative of f(x) at a, and x is the value we want to approximate.
In this case, we want to approximate g(1.99) and g(2.01) using the information given.
We know that g(2) = 5, so we can use a = 2 in the formula above.
We also know that g'(x) = Vx^2 + 5 for all x, so g'(2) = V(2)^2 + 5 = 9.
Therefore, we have:
L(1.99) = g(2) + g'(2)(1.99-2) = 5 + 9(-0.01) = 4.91
L(2.01) = g(2) + g'(2)(2.01-2) = 5 + 9(0.01) = 5.09

Solve the linear inequality. Express the solution using interval notation.2 − 4x > 6Graph the solution set.
The solution set for the inequality 2 - 4x > 6 is x < -1, expressed in interval notation as (-∞, -1).
How to solve the inequality?To solve the inequality 2 - 4x > 6, we need to isolate the variable x on one side of the inequality.
2 - 4x > 6
Subtract 2 from both sides:
-4x > 4
Divide both sides by -4, remembering to flip the inequality since we are dividing by a negative number:
x < -1
Therefore, the solution set for the inequality 2 - 4x > 6 is x < -1, expressed in interval notation as (-∞, -1).
To graph this solution set, we can draw a number line and shade everything to the left of -1.
